Proof-of-concept for MooseX::Role::Parameterized support

How would you feel about adding support for MooseX::Role::Parameterized? Maybe even like below? MRP support is the only show-stopper that prevents me from switching most of our test infrastructure over from Test::Able to Test::Class::Mose, so I am more than willing to curate this feature until it is release ready.

Most likely t/tags.t is not the best place to test that feature, but for a proof of concept this was the easiest to pull of. Please also ignore the white-space changes in this file, in the unlikely event you want to merge this feature as-is, I will correct those to match the projects style.
